A pixel on an LCD screen which doesn't work!

I have a blue one and a green 1 😎

They are really small and most of the time hardly noticeable.

What's a dead pixel?

Good link, thanks; now I know what the dead one on my laptop is - dual dead subpixels, as it just displays blue, nothing else.

"1280 x 1024 x 3 = 3,932,160"
That's how many transistors the site says are in an LCD with a native res of 1280x1024. They say it's almost inevitable to have any dead transistors? CPU's have up to 55 billion or more, with upcoming videocards looking at even more in the GPU. As I understand it, even one dead transistor can lead to errors or crashes. How do they manage such a great success rate, yet LCD manufacturers can get by selling defective products and call it acceptable?

I think CPUs/GPUs do indeed have many dead transistors in them, but the dead transistor is probably one of a few transistors that does the same thing (redundant transistors?) and that's why they'll still work even though some transistors are dead.

But I'm not a microelectronics expert so I might be wrong 😛
